I am a big fan of co-op in my FPS games, mainly because I suck too hard to get through one completely on my own and am a big fan of saying, "You guys go on up ahead, I'll guard the rear." Tragnarion Studio's new game The Scourge Project promises much rear-gaurding to be had. The Unreal Engine 3 developed FPS is being built from the ground up with a focus on co-operative gameplay, with up to four players each playing a character with their own unique story rather than being four of the same guy with different skins. The game is being developed for PCs and consoles for a release sometime next year, and should we happen to get a chance to play together I assure you I'll be behind you 100%.
